Described as "especially glorious... ethereal" by Whole Note, and "a highlight of the concert" by the Boston Musical Intelligencer, the music of Canadian composer Tawnie Olson draws inspiration from politics, spirituality, the natural world, and the musicians for whom she composes. She has received commissions from the Canadian Art Song Project, Third Practice/New Music USA, the Canada Council for the Arts, Mount Holyoke College/The Women’s Philharmonic, the Blue Water Chamber Orchestra, Ithaca College, the American Composers Forum, and the Yale Institute of Sacred Music’s Robert Baker Commissioning Fund, among others. In 2017, she received an OPERA America Discovery Grant to develop a new work about Hildegard of Bingen and Eleanor of Aquitaine with re:Naissance Opera (libretto by Roberta Barker), and a Canada Council for the Arts Professional Development Grant to study field recording at the Cornell Lab of Ornithology. In 2018 she is the Composer-in-Residence of the Women Composers Festival of Hartford and an American Composers Forum BandQuest Composer-in-Residence at E.C. Adams School in Guilford, CT. She is the winner of the 2015 Iron Composer Competition, and her Three Songs on Poems by Lorri Neilsen Glenn took second prize in the 2018 NATS Art Song Competition. She is a 2018 Connecticut Artist Fellowship recipient and has won awards from SOCAN and The Guelph Camber Choir/Musica Viva.
